CHAIN-SAW MACHINE I Specification of Letters Patent. Patented 114 1916i Application filed Ju1y3, 191-1. Serial No. 636,651.

To all whom it may concern:

Be it known that I, -MABLON G; SALLEE,

a citizen of the United States, residing'at Springfield, in the county of Greene and Stateof Missouri, have invented certain new and useful Improvements in Chain-Saw Machines, ,of which fobjects the provision of an improved condriving ge ar,-Fig. .3, a detail view of the secured to the spindle. of sprocket wheel 2.

, struction of frame for the machine and imdriving sprocket, and .Fig, 4, a fragmental view of the saw chain, In the"drawings similar reference characters will be used to designate correspondingparts throughout the several views.

he frame 1 of my improved machine is as shown-formed of an angle or T beam to insure rigidity with the least expenditure of material and having a substantial U-shape with flanged wheels 2 and 3 journaled on the ends of the beam and another flanged wheel 4 secured in a slot in arm 5 fastened at the curved middle portion of the beam and ex-, tended laterally therefrom, Wheel 2 is pro.-

vided with sprocket teeth 6 spaced from its 7 indicates a stud shaft journaled on frame 1 and having azbeveled gear, wheel 8 secured thereto that meshes with a beveled pimon 9 the following is a specificaplan view of my iinproved.

10 indicates a drive shaft journaled on framel, that is driven by any suitablepower and 11 a chain and. sprocket gearing connecting shaft 10 with stud shaft 7 12 indicates an operating handle secured to frame 1.

The saw chain is made up of links 13 connected by plates 14 pivotally secured to the ends of the links and having pins or lugs 15- c'onnecting them that ride in slots 16 in the links, said pins and slots serving to the pivotal movement of the links to a circle described by the periphery of the wheels 2,

3 and 4 so that in rounding these wheels the pull isexerted by the pins 15 'and on the ends-ofthe slots, as well as by the pivot pins 17. The inner edges of the links 13 are curved as shown at 18 to fit the periphery of the wheels 2, 3 and 4.

' 19 indicates notches in the two ends of the links 13 that combinewith the plates 14 to form sockets toreceive the teeth 6 of the sprocket wheel 2. v

In operation the saw frame is supported in any suitable manner and is controlled by handle 12. Power is applied through shaft 10 and is transferred to the saw chain through gearing 11, stud shaft 7, beveled pinions 8 and 9and sprocket wheel 2. Having thus described my invention what I claim is- A chain saw comprising links having slots adj acent'each end and having right angled notches in their bottom ends, and plates connecting said links, said plates'being pivoted to said links adjacent said right angled notches and having lugs vadjacent their top for insertion in said slots.

*In testimonywhereof I hereto afiix my signature inthe presence of twowitnesses.
